I just noticed that there's no matching acm_put_dest() to this call. I'll fix
this up.

Rather than skipping addresses that we can't lookup the GID for, I *think* it
would work to simply add new_dest, but set the state to ACM_ADDR_RESOLVED.
I can quickly throw a patch together to this effect, but won't be able to test
it immediately.
